However, the bulk cheese is mostly cut and sold at retail/deli counters in random weight packages. The brand name and lot code information of the original bulk cheese may not appear on the individual cut pieces of the cheese. Consumers are advised to contact the retailer to determine if they have the affected cheese.

These products have been distributed nationally.

Remember, food contaminated with Listeria may not look or smell spoiled. Be safe.
